Title: Electric-resistance-welded tube excellent in sulfide stress corrosion cracking resistance
Inventor: YAMAMOTO YASUSHI
IPC: C22C38/06
Filed: 1992-07-27
Abstract: PURPOSE:To obtain an electric-resistance-welded tube suitable for use under a wet environment containing hydrogen sulfide, such as oil well and gas well, by specifying the deoxidation product in the electric resistance welded zone of a steel having a specific composition containing specific amounts of S, O, and Ca and also specifying hardness in the electric-resistance-welded zone. CONSTITUTION:An electric-resistance-welded tube is produced by using a steel having a composition consisting of, by weight, 0.05-0.35% C, 0.02-0.50% Si, 0.3-2.00% Mn, 0.0005-0.0080% Ca, 0.005-0.100% Al, and the balance Fe. In this electric-resistance-welded tube, the contents of S, O, and Ca satisfy the relation in inequality 1.0<=(%Ca)[1-72(%O)]/1/25(%S)<=2.5 and the deoxidation product is a multiple inclusion of (CaO)m(Al2O3)n. Moreover, the molecular component ratio is in the range of m/n<1, and the maximum value of the measured value of hardness in the region within 30mm on both sides, acrossing the electric resistance-welded abutting surface, is regulated to 250 or a lower Vickers hardness, and the difference between the maximum value and the minimum value is regulated to 30 or less Vickers hardness. By this method, the occurrence of SSC in the electric-resistance-welded zone, originated from hydrogen blister cracking perpendicular to the plate surface, can be prevented.

Title: Optical filter
Inventor: NAKAZATO KOJI
IPC: G02B6/00
Filed: 1991-08-29
Abstract: PURPOSE:To obtain an amplifying optical filter for enhancing an optical multioplication factor in the band of 1.3mum wavelength and the other bands by removing unnecessary light disturbing the amplifying of light. CONSTITUTION:The prescribed part of an optical fiber 20 provided with a core made of an optical functional glass that Pr is added as an active material, keeps a constant curvature by a holding means 22. Therefore, the light of the longer wavelength side than specific wavelength, out of propagation light transmitting the optical fiber 20, is attenuated. When the necessary light such as excitating light, and light, enter the one end of the optical fiber 20, the excitating light excites the Pr. excited Pr emits the unnecessary light together with necessary emission light having the same wavelength as that of the signal light, etc., but the unnecessary light is attenuated on the prescribed part of the optical fiber 20. Therefore, the emission of necessary induced emission light having the same wavelength as that of the signal light caused by the emission of the unnecessary light can be prevented.

Title: Lead-acid secondary battery
Inventor: HASEGAWA TOSHIAKI
IPC: H01M2/04
Filed: 1990-08-20
Abstract: PURPOSE:To prevent charging with static electricity and damaging a battery due to discharging spark by putting a layered body consisting of an insulating layer in the surface and a non- insulating layer in the inside or the lower part on the upper face of a cover, covering liquid inlet parts, and connecting it with an automotive body. CONSTITUTION:A layered body 1 consisting of an insulating layer 3 in the surface and a non-insulating layer 2 in the inside or the lower part is put on the upper face of a cover 6 and at the same time, liquid inlet parts are covered with at least this layered body 1 and it is connected with an anode terminal 5 or an automotive body containing metal fittings for fastening a battery. In other words, the layered body 1 is opened at the spots corresponding to the liquid inlet parts 4 and at the same time has a shape having a hole for connecting with an anode terminal 5 and is stuck to the upper side of the cover 6. Consequently, even if charging with static electricity and discharging spark are generated in the periphery of the liquid inlet parts 4, they are earthed to the automotive body through the non-insulating layer 2 of a metal film of the layered body 1 and the anode terminal 5. Also, since the non- insulating layer 2 is insulated by the insulating layer 3 at the surface, short-circuit is not caused even if a metal body such as a driver. etc., exists between the non-insulating layer 2 and the insulating layer 3. As a result, damaging of a battery is prevented.

Title: Electronic balance
Inventor: NAGANE YOSHIKAZU
IPC: G01G23/48
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a reliability to a weight display when an environment temperature in the periphery of an electronic balance suddenly changes. SOLUTION: An environment temperature Tc in the periphery of an electronic balance is always detected by a temperature sensor SN3 and the temperature data are directly input to a central processing apparatus 22. At the same time, the temperature data are output also to a temperature change rate-judging means 23. The means 23 calculates a change amount α, per unit time of the measured temperature (an inclination of a graph) from clock data from a clock 24 and judges a temperature change. When the α is not smaller than a preliminarily set threshold αS, a system which carries out correction with the use of a correction value cannot cope with the situation, and in this case the number of digits of a weight measurement display is reduced via an accuracy display- changing means 26.  When the α is not larger than the threshold αS, correction is possible and a correction value corresponding to the measured temperature Tc is selected from a correction value memory means 25, so that a corrected weight is displayed.
